SPECIFICATION formingpart of Letters Patent NO. 451,573, dated May 5,1891.

Application filed November 25, 1890. Serial No. 372,582. (No model.) I

' To ctZZ whom it may concern.-

Be it known that I, WILLIAM RENNYSON, a c tizen of the United States,residing at Norristown, in the county of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements inTypelVriting Machines, of which the following is a specification,reference being had therein to the accompanying drawings, in whichFigure 1 represents a side elevation of a funnel-shaped cup providedwith my im proved directrix; Fig. 2, a bottom view thereof; and Figs. 3and 4, respectively, sectional and bottom views of the device attachedto the guide-opening of an ordinary type-writer.

The invention is particularly designed for employment in connection withmy former patent, numbered 403,07 5, dated May '7, 1889, in which afunnel-shaped cup is employed to guide the type-bars to their properpoint upon the impression-surface; but it may with equal advantage beapplied to any machine wherein pivoted type-bars are used, and it isnecessary that all the bars be guided without injury to theirprinting-characters to a certain point upon the impression-surface, aswill be more fully hereinafter set forth.

The invention has for its object the provision of an extremely simpledevice for accurately guiding the type-bars to their proper point .uponthe impression surface; and it consists of a series of radially-arrangedlaterally-yielding springs or sections applied to an openi'n'g iin asupport held in close proximity to the printing-surface, whereby thetype-bars will all be accurately guided to the same point and all wearof the type-bars or springs compensated for, and whereby different-sizedtype-bars may be accommodated, as will presently appear.

In the drawings, a designates a funnel, which is'supported in anysuitable manner in close proximity to the printing-surface, and whichmay be arranged, as shown, to print upon a matrix or surface below, oritmay be inverted when it is desired to print upon a surface arrangedabove it. Secured to the inclined exterior of this cup are a pluralityof springs h, (preferably four,) which are arranged radially withrespect to the smaller opening of the funnel, and which extend over theopening and terminate equal distances from its center. The inner ends ofthe springs preferably do not touch each other; but they may be adjustedto contact with each other, if desired. The springs are securedadjustably to their support by means of slats and screws in order thatthey may be accurately adjusted with respect to the center of theopening to which they are applied, and also in order that they may beadjusted at intervals to compensate for wear of the parts.

The yielding sections may be applied with equal advantage to theguide-openings of the ordinary type-writin g machines, as shown in Figs.3 and at. In these figures the springs are shown adjustably secured tothe under side of the support a, and bent or turned up into the openingtherein a suitable distance. The support a may be secured to the frameof the machine in any suitable manner.

The advantages of this manner of guiding the type-bars are obvious. Theyielding sections will accommodate various-sized typebars and guide themall to the proper point upon the impressionsurface, thereby keeping thecharacters in perfect alignment, whether the type-bars all be of thesame size or not. This feature of adapting itself to type-bars ofdifferent shapes and sizes is importantin that it will not be necessaryhereafter to get all the bars exactly the same size, and it is alsoadvantageous for the reason that some of the type-bars, being used morethan others, become worn and reduced in diameter and would therefore betoo small for the guideopening if some means were not-provided tocompensate for such wear. It is also obvious that wear and friction willbe reduced to a minimum by employing these yielding sections, and alsothat there will be less danger of injury to the type or characters.

Inasmuch as the feature of the invention is to provide a yielding andvariable guideope'ning for the type-bars, it is obvious that thearrangement of the springs may be varied without departing from theinvention. For instance, one of the springs or sections may be maderigid, if desired, in order to insure the perfect alignment of theletters.

I am aware that it is not new to arrange around a type-opening a seriesof radial pivoted dogs for the purpose of centering the type, andtherefore do not broadly claim such construction.

The peculiar advantage of my rigidly-so cured springs is that saidsprings serve to positively guide the type to the proper point and atthe same time yield sufficiently laterally to readily accommodate typeof diiterent sizes. Furthermore, there are no pivots to wear loose, andthe elastic sections may be readily adjusted with respect to the centerof the guide-opening to compensate for wear and to properly center thetype.

Having thus fully described my invention, what I claim is- 1. Thecombination of a support having an opening for the passage of thetype-bars, and a series of radially-arranged springs rigidly secured tothe said support and having their free ends extending to near the centerof the said type-opening in the support, substantially as described.

2. The combination, with a support provided with an opening for thepassage of the type-bars, of a directrix consisting of aseries ofra-dially-arranged sections rigidly secured to the said support andhaving their free ends terminating nearly in line with the center of thesaid type-opening, one or more of the said sections being elastic at itsfree end, as and for the purposes described.

3. The combination, with a support having an opening for the passage ofthe type-bars, of a dircetrix consisting of a series of radiallyarrangedsections rigidly and adj ustably secured to the said support and havingtheir free ends terminating nearly in line with the center of the saidopening, one or more of the sect-ions being adapted to yield atits freeend, substantially as described.

et. The combination, with a funnel provided with a guide-opening for thetype-bars, of a series of radially-arranged springs adjustably securedto the smaller end of the same and having their free ends terminatingnearly in line with the guide-opening, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
